Inspiration

Screen-time numbers are easy to ignore. We wanted your habits to become something you could actually see and care about.

What it does

Wasting time on phone weakens Doomo; studying and completing small real-world quests help him recover.

How we built it

We used Codex and GPT-5.6 with React Native, Android usage data, an offline behavior engine, and spaced-repetition study cards.

Challenges we ran into

Making Doomo motivating without making the user feel judged and keeping Android tracking reliable and battery-friendly.

Accomplishments that we're proud of

We turned screen habits and learning progress into an emotional companion instead of another analytics dashboard. The isometric room was also cool.

What we learned

People respond more strongly to a character that reflects them than to charts, warnings, or screen-time limits.

What's next for Doomo

More expressive animations, smarter study-card generation, and deeper changes to Doomo’s room and personality. Integrating google classroom for more personalized feel and realtime conversation. Migrate to android native for more control.
